Ads/cft Definition and 56 Threads

I have a question about Witten's original 1998 paper on AdS/CFT http://arxiv.org/abs/hep-th/9802150 Since the AdS metric diverges at the boundary, the boundary metric is only defined up to a conformal class Eq. (2.2), ds^2 \to d\widetilde{s}^2 = f^2 ds^2 Similarly, the solution for...

Does anyone have a simple explanation for this?

Hello everyone! I'm studying string theory at a graduate level and want to focus on ADS/CFT correspondence. The problem is that I don't know where to start from. I've already learned the bosonic string, some elements of CFT (and BRST quantization), T-duality and how the D-Branes enter the...

Hi! I am a bit confused about the AdS/CFT conjecture... One of the things I don't really understand is when N=4 SYM is a valid description of the D-brane dynamics. My impression was this: In the open string picture of branes, the massless excitations of the open string connected to the...

Hi, this is my first post. I've been studying the AdS/CFT correspondance recently, and though I am familiar with the relativistic calculations required, the aspects of the conformal field theory are still new to me. Does anyone know a good primer for such material? Namely, I am interested in...

I have a few questions about something I read in the http://pancake.uchicago.edu/~carroll/hawkingdublin.txt of Stephen Hawking's talk at GR17. He says that it has been claimed that the information paradox can be resolved by a duality between supergravity in anti de sitter (AdS) space and a...
